And, the AA-grafted PET fabrics have the best hydrophilicity in three monomers. Then, we treated AA-grafted PET fabrics with PU finishing solution under paddry-cure process and we found when the grafting poercentage is increasing, the PU add-on、hydrophilicity and durability becoe higher. And the non-sodaed grafting fabrics have better hydrophilicity and durability when they grafted by monomers. The thermoreactive waterborne PU pre-prepolymer containing PEG/PCL ratio 1 mixed with nonionic PU have durable hydrophilicity under pad-dry-cure process.
